OBS

Les câblodistributeurs ont traditionnellement distribué leurs signaux dans un même sens, c'est-à-dire en aval, vers les foyers des abonnés. En installant des amplificateurs à rebours dans le boîtier d'amplification, le système de câblodistribution peut aussi porter des signaux en amont à partir des foyers des abonnés. La transmission bidirectionnelle facilitera, à l'avenir, les services interactifs.

Key term(s)
  • transmission bidirectionnelle
